The moon arose because in the early days of our solar system a right to object popped the earth, says an international team of researchers.
The fact that the moon formed after a planet-like object named Theia was crashed into the earth, is something that most scientists can find themselves in it. But what kind of collision was that exactly? A frontal action, the American scientist Edward Young and his colleagues in response to new research.

Earlier seemed a collision at an angle of 45 degrees or more likely. That conclusion you can directly draw from the fact that the relationships between the various oxygen isotopes in moon differed from those of the earth, as the German geologist Daniel Herwartz and his team noted in 2014.
Young and his team oxygen ratios which have now re-examined. On the one hand they studied the composition of seven moonstones, brought back by the Apollo missions, and a meteorite from the moon. On the other hand they took six stones from the mantle of the earth under the microscope.

Their conclusion:. there is, contrary to what Herwartz and his followers claimed, as well as no difference between the oxygen proportions in the moon, and in which the earth. And that does not rhyme with a collision at an angle; then the largest part of Theia ended up at the moon. Was the frontal collision, however, reports a press release from the University of California in LA, it would have ensured that the Theia material evenly between earth and moon was divided. The result is the same oxygen ratios that Young and his team have now measured
